This Customer Wanted the Quietest System Possible — Here’s Our Custom Solution

Providing Optimal Comfort with an Ultra-Quiet System: The AirGreen Solution for a Demanding Client

When a client in Montréal contacted us with a specific request — to install a heating and cooling system that was as efficient as it was invisible, but most importantly, silent — we embraced the challenge with enthusiasm. Many people underestimate the importance of noise levels in an HVAC system, but for this customer, it was a determining factor. Here’s how we designed a custom solution to meet her expectations while optimizing both thermal comfort and the silence of the unit.

The Client’s Specific Needs

The client, a homeowner in a mid-sized house in Montréal, was looking for a heating and cooling system that could maintain a comfortable temperature year-round without generating annoying noise. She had tried a conventional system in the past, but it emitted sounds she found unbearable, especially during hot summer nights and cold winters.

She specified that she wanted a modern system that provided maximum performance while being discreet. After considering the constraints of her home, we began researching the heat pump model best suited to her needs.

The Choice of Equipment: Fujitsu KZAH R-32 Heat Pump and Its Noise Reduction Technology

After conducting a full assessment of the home, we recommended the Fujitsu KZAH R-32 heat pump. This model was selected for its ability to combine energy efficiency with silent operation.

Why the Fujitsu KZAH R-32?

  • Inverter Technology: This technology allows the unit to modulate its speed and run more smoothly, thus reducing noise fluctuations.

  • R-32 Refrigerant: This more modern refrigerant is not only more environmentally friendly, but also allows for better energy performance.

  • Extremely Low Noise Level: The indoor unit of the Fujitsu KZAH R-32 emits less than 22 dB, equivalent to the sound of a quiet conversation, making it ideal for noise-sensitive environments.

  • Year-Round Efficiency: Whether in heating or cooling mode, this model guarantees a constant temperature, even in the extreme winter conditions of Montréal.

The Installation Process: A Custom Approach

Installing this type of system required careful planning to ensure not only performance but also absolute silence.

1. Assessment of Spaces and Acoustic Constraints

The first step was to evaluate the acoustics of the house. Given the client’s specific request, we carefully examined each room where the indoor unit could be placed. We chose a strategic location for the indoor unit, ensuring minimal impact on the living spaces, particularly the bedroom.

2. Installation of the Outdoor Unit: Discretion and Efficiency

The outdoor unit of the heat pump was placed at the rear of the house, far from the bedroom windows. We also opted for a vibration-dampening mount to reduce operational noise.

3. Sound Level Testing and System Calibration

Once the installation was complete, we conducted sound level tests to ensure the unit was operating in full compliance with the client’s expectations. We also calibrated the system to ensure it ran at peak efficiency without disturbing the ambiance of the home.

Results Achieved: Exceptional Comfort with Total Silence

After the installation, the client immediately noticed the difference. Here are the main results she shared with us:

  • Absolute Silence: She was able to enjoy nights without the annoying sounds from her old systems.

  • Thermal Performance: The house is now comfortably regulated year-round, whether during the summer heat or winter cold.

  • Energy Savings: Thanks to the Inverter technology and R-32 refrigerant, energy consumption was reduced by 20% compared to her previous system.

  • Clean and Discreet Installation: No visible changes to the home’s aesthetics; everything was done to preserve the interior’s visual integrity.
